A method for producing an automotive glazing with an optical sensor device, with the glazing having superior optical qualities, including the steps of applying an enamel obscuration mask on at least one face of at least one glass sheet, where the obscuration mask extends to an area where the at least one optical sensor device will be fixed and includes at least one opening on the automotive interior side so as to be capable of acquiring information through the opening from the optical sensor device intended to be fixed at the at least one opening; drying or firing the enamel obscuration mask; applying a washable cover layer resisting at a temperature of at least 620° C. on the surface of the at least one opening; submitting the glass sheet to a heat treatment above 450° C. during a bending or tempering process; and removing by washing the washable cover layer.

Provided is a Low-E glass plate protection method capable of preventing or inhibiting Low-E layer alteration. The protection method includes a step of applying a protective sheet to a surface of a Low-E glass plate having a Low-E layer comprising a zinc component. Here, the protective sheet has a PSA layer. The Low-E layer comprises a zinc component. The PSA layer includes ammonia and an acid or acid salt capable of forming a counterion to an ammonium ion.

A process for the manufacture of a heat strengthened glass substrate, includes the application of a temporary layer including a polymer on a glass substrate including a glass sheet, then the application to the glass substrate coated with the temporary layer of a treatment for the heat strengthening of the glass including heating, leading to the removal of the temporary layer, and then cooling by blowing of air through nozzles. The glass substrate thus obtained exhibits a reduced level of iridescences.

A protected substrate includes a planar substrate having a surface and a burn-off temporary protective layer positioned over at least a portion of the surface. The burn-off temporary protective layer includes a polyurethane layer, an epoxide layer, or a combination thereof. The burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface. Various other protected substrates and methods for protecting a substrate are also disclosed.

The present invention provides a metal-carbon composite of a core-shell structure and a method of synthesizing the same. The method includes preparing a first polymer-covered glass substrate with a nano-thickness metal film deposited thereon; immersing the first polymer-covered glass substrate with the metal film to delaminate one or more 2D freestanding organic-metal nanosheets from the first polymer-covered glass substrate; transferring the one or more 2D freestanding organic-metal nanosheets onto a second target substrate; and annealing the one or more 2D freestanding organic-metal nanosheets to decompose an organic portion of the organic-metal nanosheet into an amorphous carbon-containing shell forming a metal-carbon nanocomposite of a core-shell structure.

A temporary protective coating for heat treatable coated glass article includes acrylic monomers or solid particle reinforced acrylic monomers is disclosed. The temporary protective coating of the present disclosure is completely devoid of oligomeric acrylates. The temporary protective coating is applied directly over a functionally coated transparent substrate to protect the coated substrate during heat treatment and handling of the coated substrate before heat treatment. The temporary protective coating is completely removed during the heat treatment leaving behind no residues thereby keeping the physical properties of the functionally coated substrate intact.
